Our images support multiple architectures such as `x86-64`, `arm64` and `armhf`. We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate `<external>:<internal>` respectively. For example, `-p 8080:80` would expose port `80` from inside the container to be accessible from the host's IP on port `8080` outside the container.
## Environment variables from files (Docker secrets)
You can set any environment variable from a file by using a special prepend `FILE__`.
As an example:
```
-e FILE__PASSWORD=/run/secrets/mysecretpassword
```
Will set the environment variable `PASSWORD` based on the contents of the `/run/secrets/mysecretpassword` file.
## Umask for running applications
For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional `-e UMASK=022` setting.
Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up [here](https://en.wikipedia.org/wiki/Umask) before asking for support.
When using volumes (`-v` flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user `PUID` and group `PGID`.
+ For all updates you should pull the latest image, clear all files and folders in /config and /data and reinitiate the database import by (re)starting the docker. We do not officially support upgrading this container in place with existing data sets.
+ **If you did not set WEBADDRESS env variable, then AFTER iniatilisation is complete you will need to edit the line `sub WEB_SERVER { "localhost:5000" }` in file /config/DBDefs.pm changing localhost to the ip of your host, this is to allow css to display properly**
* You must register here to receive a MusicBrainz code to allow you to receive database updates, it is free. [Get Code here](https://metabrainz.org/supporters/account-type).
* The initial import and setup of the database can take quite a long time, dependant on your download speed etc, be patient and don't restart the container before it's complete.
* It appears there are issues with unraid and using /mnt/user/cache/appdata instead of /mnt/cache/appdata, use /mnt/cache/appdata.

We publish various [Docker Mods](https://github.com/linuxserver/docker-mods) to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.
